BEAM-FRAME FOR CONTINUOUS CONCRETE GIBDERS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed April 30, 1907l Serial N0. 371,137.

To all 'whom it may concern:

Be it known that I, HUGO HAIss, a subject of the Emperor of Germany, residing at Pittsburg, in the county of Allegheny and State of `lennsylvania, have invented certain new and usefulA Improvements in Beam-Frames for Continuous Concrete Girders, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in beam frames for continuous concrete girders, and the invention relates more particularly to anchors and fastening means for bracing and connecting the ends of two beam frames.

The present invention is designed for connecting the `ends of the beam frames disclosed in my pending application filed April 20, 1907, Serial No. 369,257, where in I .have illustrated and described universal beam frames or girders to prevent sagging, cracking and shearing of concrete beams or girders.

The detail construction entering into the present invention will be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to the drawing forming part of this specification, I have illustrated a perspective view of my improved beam frames.

In the drawing, 1 indicates the intermediate housings, and 2 the end housings, these housings being connected by the ends 3 and 4 of two horizontal layers of rods or bars 5. The intermediate housings 1 and end housings 2 are provided with supporting plugs 6 and separating plugs 7.

Thepresent invention particularly resides in making the girders continuous by providing the intermediate housings 1 with locks, said locks being supported upon the intermediate housings by brackets 8EL and nuts and bolts 9. Passing through the locks S are rods or bars 10 having their outer ends bent downwardly into the concrete beams 11, as at 12, and headed, as at 14. The rods or bars 10 and their headed ends are adapted to brace the intermediate housings 1, and at the same time the end housing 2, through the medium of the ends 3 and 4 of the rods or bars 5.

From the foregoing description it will be 0bserved. Y that the rods or bars l0 practically form a bridge for the confronting ends of two beam frames, my improved anchor and fastening means dispensing with the use of wire heretofore employed for connecting the reinforcements of concrete beams.

It is obvious that twisted bars or rods can be used in connection with my improved anchor or fastening means, and I desire it to be understood that the anchor can be made of any desired size and proportion.`

What I claim and desire to secure by Letters Patent,

The combination with beam frames having end heus ings, intermediate housings, and rods or bars extending through said housings, of a plurality of rods or bars extending through said intermediate housings, over said end housings, said rods or bars having their ends bent downwardly and headed in close proximity to the first mentioned rods or bars.

In testimony whereof I ax my signature in the presence of two witnesses.
